Which of the following statement(s) regarding hydrocarbon occurrence is/are CORRECT?
Show Hint
- Gandhar field is in Cambay basin.
- Oil and gas occur in Mesozoic reservoir rocks in Bombay High field.
- Digboi field is in Assam basin.
- Hydrocarbon occurs in limestone reservoir in Ankleshwar field.
The Correct Option is A, C
Solution and Explanation
- Gandhar field: Located in Cambay Basin (Gujarat), producing oil and gas from Tertiary sandstones.
- Bombay High: Offshore field with hydrocarbons in Tertiary carbonate rocks (not Mesozoic).
- Digboi field: One of India’s oldest producing fields in the Assam–Arakan Basin.
- Ankleshwar field: Hydrocarbon accumulation in limestone and sandstone reservoirs (Cambay Basin).
Step 2: Conclusion.
Thus, the correct statements are (A), (C), and (D).
